| 中文摘要 | Microstructure and hardness were investigated in pure Al samples with different purities (5N: 99.999%, 4N: 99.993%, and 2N: 99.7% in weight) subjected to dynamic plastic deformation at cryogenic temperatures. The saturated sizes of refined grains/subgrains in these samples induced by plastic deformation are about 240 nm without an obvious impurity effect, but the dislocation density in 2N Al is evidently higher than that in other samples. Boundary misorientations for 5N and 4N Al are below 10 degrees with average values of 2-3 degrees, while the average misorientation for 2N Al is obviously larger, being about 14 degrees. Microhardness of LNT-DPD 2N Al is higher than that of 5N and 4N Al, owing to the enhanced dislocation density as their grain/subgrain sizes are almost identical. |
